Half-sider budgerigar

So, budgies are little birds that can be different colors like blue, yellow, or green. Sometimes their feathers can be half one color and half another color. When a budgie has feathers that are half one color and half another color, they are called a half-sider budgerigar. It's like they have two different colors on their body. Just like how you have different colored clothes you can wear, budgies can have different colored feathers. So a half-sider budgerigar is just a budgie with two different colored feathers on their body.
